A brief (or quite lengthy) autobiography can go in the center column of this page. You may want to insert a photo or two in this side column. You can also insert photos in the center column.
If you're inserting a lengthy biography, you should probably do it with several consecutive text boxes. This will make editing easier and will allow you to have occasional bold headers separating the text.
To use several text boxes, simply click the "Add text" box at the top of the center column. (You must be in Edit Mode to see that box.) Insert your first few paragraphs and save. Then click the "Add text" box again for your next block of text.
You can then position the text with the little arrows that appear in the blue boxes directly above the text.
Add headers with the "Add header" box and position them in the same way.
This information also appears in the Help section in the toolbar at the top of the page. Delete this entire entry by clicking the small blue "Delete" box that appears directly above this entry when you're in Edit Mode.
If you've already included all the bio you want on your home page, then this page can be used for something else. Simply rename it.
To rename this or any page, click the "Edit menu" box directly above the navigation bar (the navigation bar says "Home, My Works, Biography, etc." on it). You must be in Edit Mode to see the "Edit menu" box. Enter a new name for the section and save it.
While you're editing the menu, you may want to hide sections that you're not yet using.
To complete the renaming of this section, click the "Edit page title" box in the center column of this page.
This space is intended for an autobiography.
